If you're just going to be fetching images, I would use Image::Grab instead of LWP::Simple. Of course, TMTOWTDI, and this way would be mine. =)

Here's some example code. There's more in the POD documentation, of course.
use Image::Grab; $pic->url('http://www.example.com/someimage.jpg') $pic->grab; open(IMAGE, ">image.jpg") || die"image.jpg: $!"; binmode IMAGE; # for MSDOS derivations. print IMAGE $pic->image; close IMAGE;

It also supports a regex feature, which would be handy if you are unsure of the file extension of the image you're grabbing.

You can isntruct it to search a paticular document on a website, and it will go through all IMG tags to find an image matching your regex. It will then request it using the document's URL as it's referrer.

Something like would look for all .png images, but of course you can change this to match a filename you don't know the extension of. Could be handy for documents that change the types of images they use, for some bizarre reason. =)

$pic = Image::Grab->new(SEARCH_URL=>'http://localhost/gallery.html', REGEXP =>'.*\.png');
